System Connections

Setting the AC voltage selector

Check the setting of the AC voltage selector located on the rear panel before plug-

ging the unit into an AC socket. If necessary, adjust the selector to correspond to the

AC power voltage used in your area.

Turn the selector with a screwdriver until the appropriate voltage num-

ber appears in the window (110 V, 127 V, 220 V or 230 V - 240 V AC).

Connecting the AC power lead

After making all connections, plug the unit. If you plug the unit first,

the unit will enter the demonstration mode.

Note:

nect the unit using the AC plug adaptor supplied with the unit, as illustrated. The AC

plug adaptor is not included in areas where the AC wall socket and AC power plug

can be directly connected (see illustration ).

Setting the FM/AM span selector

The International Telecommunication Union (ITU) has established that member coun-

tries should maintain either a 100 kHz or a 50 kHz interval between broadcasting fre-

quencies of FM stations and 10 kHz or 9 kHz for AM station. The illustration shows

the 50/9 kHz zones (regions 1 and 3), and the 100/10 kHz zone (region 2).

Before using the unit, set the SPAN SELECTOR switch (on the rear panel) to the

interval (span) of your area.

To change the tuning zone:

Items adjusted automatically

(1) Offset adjustment (The offset voltage between the head

amplifier output and the VREF reference voltage is

compensated inside the IC.)

* Focus offset adjustment

* Tracking offset adjustment

(2) Tracking balance adjustment (waveform drawing

Fig.14-2 EFBL)

(3) Gain adjustment (The gain is compensated inside the IC

so that the loop gain at the gain crossover frequency will

be 0 dB.)

* Focus gain adjustment

* Tracking gain adjustment

• Adjustment

Since this CD system incorporates the following automatic

adjustment functions, readjustment is not needed when

replacing the pickup. Therefore, different PWBs and pickups

can be combined freely.

Each time a disc is changed, these adjustments are

performed automatically. Therefore, playback of each disc

can be performed under optimum conditions.

Parts code

1. CD optical pickup Lens cleaner disc UDSKA0004AFZZ

HOW TO USE

CAUTION

Cleaning fluid

Cleaner disc

Using the brush in the cleaner cap, apply 1 or 2 drops of the cleaning fluid to the

brush on the CD cleaner disc which has the mark next to it.

Place the CD cleaner disc onto the CD disc tray with the brush side down,then

press the play button.

You will hear music for about 20 seconds and the CD player will automatically stop.

If it continuous to turn, press the stop button.

The CD lens cleaner should be effective for 30-50 operations, however if the

brushes become worn out earlier then please the cleaner disc.

If the CD cleaner brushes become very wet then wipe off any excess fluid with a soft

cloth.

Do not drink the cleaner fluid or allow it to come in contact with the eyes. In the

event of this happening then drink and / or rinse with clean water and seek medical

advice.

The CD cleaner disc must not be used on car CD players or on computer CD-ROM

drives.

is prohibited by law.

TROUBLE SHOOTING

When the CD does not function

When the CD section does not operate when the objective lens of the optical pickup is dirty, this section may not operate. Clean

the objective lens, and check the playback operation. When this section does not operate even after the above step is taken, check

the following items.

Remove the cabinet and follow the trouble shooting instructions.

"Track skipping and/or no TOC (Table Of Contents) may be caused by build up of dust other foreign matter on the laser pickup

lens. Before attempting any adjustment make certain that the lens is clean. If not, clean it as mentioned below."

Turn off the power, and wipe the lens softly using a cleaning paper moistened with commercially available cleaning solution so

as not to damage it. Be careful not to touch the lens with bare hands.

Dust gradually accumulates on the objective lens during use, and it may degrade performance. To avoid this problem, use a

cleaning disc designed for CD optical pickup lenses.

When a CD cannot be played

1. "E-CD01" is displayed.

(1) Check the power to IC1 (LC78645E), the presence of the clock signal (33.8688 MHz) and the status of the RESET terminal

(pin 66 on IC1).

(2) Does the pickup move to the PICKUP-IN Switch (SW4) position?

If (1) and (2) are OK, check the system microcomputer (especially the communication line with the DSP).

2. Pressing the CD operation key is accepted, but playback does not occur.

(1) Focus-HF system check

(2) Tracking system check

(3) Spin system check

(4) PLL system check
